Which countries' patents does China recognize?

From the perspective of exercising rights, China only recognizes China patents. Even if the patent of the other party is American, Japanese or European, it is meaningless if it is not applied for and authorized in China.

I started with an international patent application, not an international one. The beginning is the abbreviation of WIPO, International Intellectual Property Organization. PCT international applications usually have a number beginning with WO, but all applications need to enter the patent offices of various countries or regions for application and examination in order to obtain patent rights. For example, the above-mentioned patents starting with WO will be given the application number of China after entering China, and will be examined by the China Patent Office. Only through examination can they enjoy the patent right in China.
